Abstract

Abstract:

To solve the problem of poor real-time and accuracy of process manufacturing monitoring, this paper proposes a visual monitoring system architecture of digital twin workshop based on production factor data, production process, and multi-process equipment entity object amid the rapid development of digital twin technology and increasingly close integration with the manufacturing industry. Twin modeling is conducted on multi-process coupling production line entity objects from multiple dimensions such as element, state, and operation logic. Based on key technologies of data collection and transmission of OPC UA (OLE for process control unified archiecture) unified architecture and real-time drive of the virtual workshop, the three-dimensional visual monitoring of the process manufacturing equipment status and the whole process of production factors is realized. Finally, the application verification is carried out based on the silk production test line of a process manufacturing enterprise. This paper provides a method and realization way to improve the predictability, linkage, and autonomy of the whole production factors in the process manufacturing.

Key words: process manufacturing, digital twin, multi-process coupling production line, object-oriented timed Petri net(OOTPN), visual monitoring
